Firefox Support Forum

For a week or better I have been unable to download anything through my Firefox browser, I have refreshed and uninstalled Firefox (I had to reinstall through another browser) in an attempt to fix this issue to no avail. I cannot download from verified sites, nor am I able to download Firefox's own extensions or themes (when I attempt I get an error telling me to check my connection, screenshot included).

I would like to be able to use Firefox normally again, with the ability to download files and install my extensions restored.

Bonjour,

Depuis plusieurs semaines, il m'est impossible de télécharger des PDF depuis firefox. J'ai essayé de faire une réparation, mais désormais j'ai également perdu mes extensions et lorsque je veux les réinstaller, on m'affiche : "Échec du téléchargement. Veuillez vérifier votre connexion." (par exemple pour ublockorigin)

Merci d'avance pour vos réponses, Cordialement Selma

I want to install the older version of Mozilla firefox for windows 11 in Spanish and Dutch language, please provide the link for Spanish and Dutch for ex. 125 version of Mozilla Firefoz

Automatic update on my Windows 10 desktop of the the new update 127.0.1 resulted in a version of Firefox that worked more or less for some web sites but was unable to reach others.'

I am seeing the message that Updates are being managed by my organization: This my computer and NO Organization manages my updates! I may have paused them while updating my OS early this week. Now running Linux Mint 21.3I am seeing the message that Updates are being managed by my organization: This my computer and NO Organization manages my updates

Hi, I‘m not sure if I selected the right topic for my question but I can‘t find an answer to my query anywhere, so here goes:

When I opened Firefox on my Mac today (all up-to-date), a pop-up request by Firefox (cf. attached picture) showed up: "Firefox needs to download the font "Weibei SC". "Weibei SC" is 17,4 MB." with the options "Skip" and "Download".

Puzzled by this odd request, I wanted to skip it, but anytime I clicked skip the window would pop up again. I never clicked on download and I actually closed and reopened the browser, without having it show up again. I even restarted my device and reopened Firefox but it didn‘t show up again.

Now, I want ro believe that there is nothing to worry about, that it was a software blunder of some sort and that maybe normally it just installs fonts in the background without me knowing. But for the sake of my own peace of mind, I‘d feel more comfortable if someone who knows the software better than I do, explain to me what this was or might have been, and hopefully that it was nothing harmful.

Thank you!

MY Windows 11 laptop crashed and OS may need to be reinstalled. Will this wipe out my Firefox browser bookmarks. I would like to save the bookmarks somehow. How do I do this without access to that system?

greetings, I had trouble with firefox crashing, so i uninstalled it and reinstalled it and now I have lost all my passwords and bookmarks from the previous installation. I have tried to fix it, but I am completely computer illiterate. Please help. I am unable to do this with directions found in my search. I need someone to do it FOR me. Please help.

Since the latest update Firefox doesn't show up in the browser list. I don't want to uninstall to reinstall because I have too many settings in my browser that I don't wish to reset. Please solve the problem.

Hi, the turbotax website forced me to update Firefox and since I did, I am no longer able to open the browser at all. The error message reads, "You can't use this version of the application "Firefox" with this version of OS X. You have OS X 10.11.6. The application requires OS X 10.12 or later." Unfortunately, from what I have read, I can't get that update that on my iMac (21.5inch, late 2009) OS X El Capitan Version 10.11.6. Is there any way to downgrade the Firefox install? I can't even see what previous version of Firefox I had before because I can't open the browser anymore. If anyone can help I would be super grateful. Thanks in advance!

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

Hi,

My computer was on during the week-end and when I came back home I noticed we had a couple of power outages. Computer restarted automatically (Win 10 22h2) and when I launched Firefox, it started as brand new with all my addons gone and none of the previous session restored (I had 4 Firefox browsers opened with each 20+ tabs opened).

I have tried looking at C:\Users\MYUSER\AppData\Roaming\Mozilla\Firefox\Profiles but found nothing of interest. Where is everything and how can I restore everything I had ?

I even tried Troubleshooting mode and downgrading to a former version of Firefox (126.0.1 64 bits).

Thanks,

Hi - I updated my Firefox / Mozilla browser yesterday and now all types of downloads are failing. PDFs and EXEs alike. I can't an error that says Failed.

And yet, when I use Chrome or Edge, the downloads work fine, soooo - not sure what is going on.

Can you please assist? Thank you!

Firefox: 127.0 (64-bit) Windows 10
